Using Median for Skewed Data and Outliers

Right-skewed distributions have a long tail of high values that pull the mean upward. The median represents what a typical observation looks like.

Income and wealth

Mean household income exceeds median because millionaires pull the average up. Policy discussions use median income to describe the typical household.

Real estate prices

One mansion in a neighborhood of modest homes makes mean price misleading. Median home price is the standard real estate metric.

Healthcare costs

Most patients cost little; a few catastrophic cases cost millions. Median spend per patient is far below mean — important for insurance pricing.

When to report both

Academic papers often report mean ± SD for normal data and median with interquartile range (IQR) for skewed data. Always check distribution shape first.
